ALEXANDER W. SKIINNER, OF PROVIDENCE, RHODE ISLAND.

Specification forming part of Letters Patent No. 135,015, dated January21, 1873.

To all whom it may concern:

Be it known that I, ALEXANDER W. SKIN- NER, of Providence, in the countyof Providence and'State of Rhode Island, have invented an ImprovedCondenser-Tube for Garding-Machines, of which the following is aspecification: V

The nature of my invention consists in a cross bar or wire arrangedcentrally across the mouth of a contraction in the bore of thecondenser-tube, or across the inner opening of a ring or tube of smallercaliber than the main tube, and at such a distance therefrom as willproduce the required degree of friction upon the roping as it is beingdrawn through. It also consists in forming the lesser caliber in aseparate tube or ring, so that the distance of the inner opening fromthe centrally-arranged cross bar or wire may be adjusted at pleasure, inorder to increase or decrease the-friction on the roping, thusregulating its size.

Figure 1 represents the ordinary condensertube with its flier. Fig. 2 isa longitudinal sectional view of the same. Figs. 3 and 4 represent oneform of my improved condensertnbe. Figs. 5 and 6 represent my improvedadjustable condenser-tube.

in Figs. 1 and 2, a a are the bearings upon which the tube A revolves. Bis the flier formed by the bent wire b, to which the crosswire I) isfastened; The roping (3 passes be tween the wires, as shown in Fig. 2.The flier B is unsatisfactory in its operation, from the lack of asufficient guide beyond the bar b to preserve the concentricity of theroping, which, on this account, is liable to fly out from its properline beyond the flier, thus causing a break in the web of which theroping' is to be formed. Also, in the adaptation of the flier B to theformation of roping of different sizes, it has been customary toincrease 13116 diameter of the bar I) by winding it with thread andfilling the interstices of the thread with wax, the whole having to berenewed every few days, at a considerable loss of time. The operation ofthe flier under such circumstances invariably produces an uneven roping,

which must result in an inferior quality of yarn, from its necessarylack of the proper uniformity. D, in Figs. 3 and 4, represents thesmaller tube, before the mouth of which is placed the centrally-arrangedcross-wire b. By means of the smaller opening D, placed beyond the wireI), the roping is kept in the proper line with the axis ot'the revolvingtube, and is not, therefore, liable to the disastrous effects of thecentrifugal force as imparted by the old flier above described. In caseswhere a uniform style of goods is to be manufactured, the device shownin Figs. 3 and 4 is sufficient; but where different sizes of yarn are tobe made, the opening of the contracted tube D, or its equivalent ring,should be made adjustable in regard to its distance from the crossbarI). In order to effect this I preferably cut a thread upon the exteriorsurface of the tube D, which fits in a female screw cut in the tube A,the proper position being rigidly preserved by means of the check-nut E.Other modes of holding the tube D in position may be used; but the oneshown is deemed the most practicable.

My improvement greatly facilitates threading the tube, since theroping-web may be caught by the hook used for the purpose and drawndirect-1y through the tube, whereas in the case of the old wire flierthe web is first passed through the tube by means of the hook, and thenpassed through the flier by the fingers, the whole machine having to bestopped during the operation; whereas with the use of my improvement thetube can be threaded up without such stoppage.

" "1." The combination of the tube A with the cross-bar b and tube D, orits equivalent, arranged substantially as described.

2. The combination of the tube A, the adiustable tube D, or itsequivalent, and crossbar 1), arranged substantially as described. ALEXANW. SKINNER. Witnesses:
